LAND-ROLLER.

SPECIFICATION forming part of Letters Patent No. 694,213, dated February25, 1902. Application filed June 8, 1901. SerialNo. 63,795- (No model.)

To all rah-0121, it may concern:

Be it known that I, J. CARROLL STARK, a citizen of the United States,residing at and whose post-ofiice address is Hamilton, in the county ofHancock and State of Illinois, have invented new and useful Improvementsin Land-Rollers,of which the following is a specification. I

My invention relates to land-rollers; and its primary object is toproduce a machine which will more evenly and/thoroughly roll farm landand lawns than heretofore produced.

In the construction of this roller the several rolls are pivotallyattached to a framework, whereby each roll may lie easily upon theground and move independently of the other, thereby adapting itself tothe undulations of the ground.

In describing my invention reference is made to the accompanyingdrawings,in which like numerals indicate corresponding parts in.

the several views.

Figure 1 is a view in perspective of 1nyin1-,

proved land-roller complete. Fig. 2 is afront elevation view thereof,and Fig. 3 is a central vertical longitudinal view of my inven- 2, and 3designate three rolls arranged in.

triangle relation to each other and atsuch suitable distance from eachother that the frontroll may turn on its center withoutstrik-v ing therear rolls.

4, 5, and 6 represent oblong rectangular frames in which the rollers arejournaled,and 7 the bearings for horizontal shafts 8, passing into thecenter of the rolls. The bearings 7 are formed in the ends of the frames4, 5, and 6 by having the central portions thereof bent to formsubstantially a semicircular recess. Metallic strips 9 are secured tothe under side of the ends of the frames and extend across the open endsof the bearings, thereby preventing aceidental displacement of theshaft. Upon the upper side of the front and rear of each frame arearranged upwardLy-projecting ribs 10. Intermediate of theends of each ofthe ribs is provided anepening for a pivot 11, which also passes throughopenings in the lower ends of a yoke which secures the rolls to themachine-frame. The yokes are arranged above the roll-frames 4, 5, and 6,at right angles thereto, and comprise two frames 12 and 13. The frames12 are arranged within the frames 13 and are arched so as to conform tothe periphery of the rolls, and their ends terminate on the inner sideof the rib 10, adjacent to the opening therein. The outer frames 13 ofthe yoke comprise a crossbar 15, to which on its under side the archedframe 12 is secured, and pending I ms 14, the lower ends of which lie-on the ciiter side of the rib 10, adjacent to the opening therein. Theroll-supporting frame is mounted upon the pivot 11, which joins it tothe yoke-frames 12 and 13, thereby allowing the roll-frames 4, 5, and 6to vibrate upon their pivots and permitting the rollers 1, 2, and 3 toadjust themselves to any unevenness of the ground. To the crossbar 15 ofthe yoke of the front or steering roll is secured a bearing-disk 16,which underlies a similar disk 17 secured to the under side of themachine-frame 18, to which the roll-supporting frames are secured.Through an opening in thedisks 16 and 17 is passed a king-bolt 19, whichis held in position bya nut 20. The rear roll frames are rigidly securedto the frame 18 by bolts or rivets which pass through the triangularframe and thence through openings in the-top cross-bar 15 of the frames12 and 13. It is obvious that mount upon this frame additional weight byplacing a substantial bottom in the triangular Lame and then placing theweight thereon. The lodge of the L-shaped sides of the frame serves as asupport for the bottom, and the flanges hold the same in position.

The top cross-bar 15 of the front roll-supporting frame 13 is formedwith an extension 24, which terminates in an eye 25. To this extension24 is hinged a tongue, which corn sists, preferably, of metallic strips26. The

rear ends of these strips extend on each side of the extension 22 andare provided with Letters Patent, is-

1. In a machine of the character described, the combination with aseries of rolls arranged in triangle position of 'oblon g framesprovided with journals for said rolls, ribs on said frames,

each having an opening therein, yokes com prising archedinner frames andsubstantial m-shapcd'outer frames mounted above said g Witnesses: rollsand having their ends extending downi ward adjacent to and on each sideof the said 1 ribs,.bolts engaging said ends and ribs, and

means for connecting the-rolls together.

2. In a machine of the character described, the combination with aseries of rolls arranged ill]. triangle position,of oblong frames ovidedwith journals for said rolls, ribs on sai frame,

, each having an opening therein, a yoke comprising an inner and outerframe -mounted v above each of said rolls, and having their endsextending downward adjacent to and on each side of the said ribs, boltsengaging the ends of'the'yoke-frames and ribs, and a. hollow triangularframe for connecting said roll-yokes together.

I In testimony whereof I aiiix my signature in presence of twowitnesses.
